I've just tried this on my other Ubuntu system and it did not work.

ORIGINAL SETUP
- initially installed with Ubuntu 7.10 with manual fix to initramfs
- two SATA drives in RAID-1 mirror
- confirmed that I could boot from 1 drive
- updated to 8.04.1
- GRUB is still installed to both drives but the initramfs change has been removed
- system will no longer boot on just 1 drive

TEST PROCEDURE
- added Hardy-Proposed to my repositories using the checkbox in Synaptic
- installed all updates
- confirmed reboot ok on both drives
- tried on just 1 drive; failure
- reconnected both drives, booted-up, ran 'sudo grub-install /dev/md0'
- confirmed reboot ok on both drives
- tried on just 1 drive; failure
- checked the file-date on /usr/share/initramfs-tools/scripts/local and it's 11-6-08

QUESTIONS
1. Are the updated modules in Hardy-Proposed? For instance, my installed version of 'initramfs-tools' is now 0.85eubuntu39.3
2. Is the failure message/prompt different than your old PPA version? I haven't been able to wait around for it to fail, I've just been watching to see if the new extended-info message is on-screen after it fails.
3. Should my 'local' initramfs file have today's date? I scanned it for the term "mdadm" and came up empty, so I suspect it never got updated.
4. Unrelated to this test, but if I'm planning to reinstall this system from scratch is there a better FS to choose for my RAID-1 than Ext3? I know that's the most stable and reliable but it really is noticeably slow and I haven't necessarily been that impressed with it's 'maturity' either. (For instance, I mistakenly ran 'e2fsck' on one of the individual drives and it corrupted my md partition table. It's a full-blown miracle I was able to figure-out how to reverse the error. Also, I keep losing the use of my swap partition after testing the degraded boot.)
